Many months ago I stumbled onto an exciting kit in which one can assemble an Altair 8800 emulator (and at a fraction of the size and weight of the original Altair). I knew I had to purchase this. I also knew that I had to reach out to the individual (Chris Davis) designing and selling these emulator kits, to learn more about the motivation behind it.

From there, I’ve promptly invested significant amounts of time to pull useful metrics out of the platform-of-record and into a format where we could make sense of them, and then use the metrics to make better choices about many aspects of development. read more
